2.5 Design and mode of operation

The measuring element, the concentric corrugated diaphragm, is clamped
between two flanges and the medium is applied on one side.

The diaphragm bulges elastically from its normal position as a result of the ap­plied pressure. The linear movement is proportional to the applied pressure. A
rod assembly on the side of the diaphragm that faces away from the medium
captures the expansion movement and transfers it to the indicator.

The measurement display is shown on a 270 W° scale.

5 Servicing

5.1 Maintenance

To ensure reliable operation and a long service life, we recommend carrying out
the following test on a regular basis:

• Check the reading.

• Checking the switch function in connection with the downstream compon­ents.

• Checking the pressure lines for leaks.

• Checking the electrical connections (terminal connection of the cable).

The precise test cycles and operating and ambient conditions need to be adjus­ted. If several components of the unit interact, all operating instructions of the
other units also need to be observed.

WARNING

Dust deposits

The device must be cleaned with a damp cloth a regular intervals to prevent
heat build-up. Cleaning intervals depend on the amount of local dust.

5.2 Transport

The measuring device must be protected against impacts. It should be transpor­ted in the original packaging or a suitable transport container.

5.3 Service

All defective or faulty devices should be sent directly to our repair department.
Please coordinate all shipments with our sales department.

WARNING

Process media residues

Process media residues in and ondismantled devices can be a hazard to

6.2 Options

Additional electrical attachments

Limit signal transmitters of the type KE and capacitive rotation angle transducer
of the type KE09 can be fitted into a housing enlarged by a corresponding bay­onet ring. The electrical connection is usually realised via a cable connection
socket mounted to the side of the casing.

Please refer to the data sheets KE and KE09 for technical data. You can re­ceive the data sheet on request or download them from our webserver

www.fischermesstechnik.de.

Fluid charging

The housing can be filled with glycerine if the casing is to operate under aggrav­ated operating conditions such as vibrations and extreme pressure fluctuations,
or in order to avoid condensate formation if used outdoors.

• Silicone oil is used in units with switch contacts.

• Paraffin oil is used in units with inductive proximity switches.

• Filling is not possible in units with a capacitive rotation angle transducer.

Needle

• Marker indicator
Settable indicator for marking the limit value in the disk.

• Drag indicator
The drag indicator is 'dragged' by the measured value indicator. As there is
no fixed connection between the two needles, one-off maximum values are
stored. The trailing needle can be reset using an adjusting dial in the win­dow.

FISCHER Mess- und Regeltechnik GmbH Technical Data | 6

BA_EN_MA15_ATEX 23 / 36

Measuring system

• O2applications 'Oil and grease'
In compliance with the requirements of the Chemical Professional Associ­ation, all parts that come into contact with the medium are cleaned (see or­der code filling fluids)

• PTFE cladding and/or PFA coating of the measuring system
In the case of highly aggressive media, all parts that come into contact with
the medium are coated with a protective sheath of PFA or PTFE. A FEP
covered O-Ring made of FKM is used for the flange seal. A suitable seal
needs to be used on the system side to seal the cladded units.

• Material
Optionally, the measuring system incl. the process connection is also made
of HastelloyC.

Zero point correction

• with a setting screw

• with a micro adjustment indicator
